U.S.-backed forces seized complete control of the Islamic State's de facto capital of Raqqa, Syria, on Tuesday, a commander told The Associated Press. Brig. Gen. Talal Sillo deemed the victory "the fall of the capital of terrorism." Fighting with ISIS militants had been pushed back to a stadium in Raqqa, the terrorist group's last stronghold in the city, and on Tuesday the Syrian Democratic Forces at last raised their flag over the base. The Kurdish YPG flag was planted in the stadium grounds. ISIS has lost massive swaths of territory this year, including the city of Mosul, Iraq, and its forces have been pushed back into the Euphrates River Valley, where experts expect the militants to make their "final stand."
